Question about 2003 Volkswagen Jetta TDI
Yesterday I began hearing a noise under the hood of my 2003 VW Jetta TDI..It seems like it's coming from a belt pulley assembly, but obviously, I'm not a mechanic, so I'm not sure. The closest VW mechanic is an hour away, and I don't want to drive it if this noise is an indication of something majorly wrong. Please help!
I would be most suspicious of the alternator pulley. These are known to have issues and will at some point just come off. You may want to check out this thread on www.tdiclub.com: http://forums.tdiclub.com/showthread.php?t=139424
Hope that helps.
BTW you can drive the car without that belt until the battery dies, you just won't have power steering or AC.

I'll have a go for you but I'm working in the dark here - it could be over 50 different faults! - Lets rule out a few.
Is the car behaving differently - or just making a noise?
Has it been serviced in the last 8 months?
Do you have power steering?
Do you have Air Con ?
I would say it may be an air-con pump, power steering pump, water pump or belt idler at the moment.
In the engine bay - are there....
Any leaks of fluid?
Any dry powdery rust marks around the pullies?
This may not be a serious fault at the moment, but may be the start of a wear problem.
Let me know the answers to the above to try and narrow it down for you.
